Unity 的Json转换_unity jsonconvert 转换json

今天讲特别基础但是在混合开发中常用的数据传递，Json格式数据 的序列化和反序列化。我就以我做的3d音乐功能为例 定义： 1.基础类型

    public class Communication
    {
        public long id;
        public string data;
 
        public Communication(long id=0, string data=null)
        {
            this.id = id;
            this.data = data;
        }
    }

2.音乐类型

 [Serializable]
    public class MusicInfo
    {
        //localCoverPath:本地缓存的封面图片地址
        //netCoverPath：封面图片的网络地址
        //name：歌曲名
        //author：歌曲作者
        //state:歌曲播放状态，0为播放，1为暂停，如果只是单纯操作播放暂停，state之外其他字段可为空
 
        public string localCoverPath;
        public string netCoverPath;
        public string name;
        public string author;
        public int state;
    }

private static bool TryParse<T>(string json, out T t)
        {
            try
            {
                var data = JsonConvert.DeserializeObject<T>(json);
                if (data != null)
                {
                    t = data;
                    return true;
                }
            }
            catch (Exception e)
            {
                Debug.LogWarning($"TryParse -> json:{json} | e:{e}");
            }
            t = default;
            return false;
        }

反序列化：

public void SetMusicInfo(string dataJson)
        {
            if (!TryParse<Communication>(dataJson, out var communication))
            {
                var errMsg = "SetMusicInfo: Invalid json -> " + dataJson;
                Debug.Log(errMsg);
                CallBackToAndroid.RequestCallBack(false, -1, errMsg);
                return;
            }
 
            if (!TryParse<MusicInfo>(communication.data, out var musicInfo))
            {
                var errMsg = "SetMusicInfo: Invalid musicInfo -> " + dataJson;
                Debug.Log(errMsg);
                CallBackToAndroid.RequestCallBack(false, communication.id, errMsg);
                return;
            }
 
            var musicSoundController = FindObjectOfType<MusicSoundController>();
            if (musicSoundController == null)
            {
                var errMsg = "SetMusicInfo: musicSoundController not init -> " + dataJson;
                Debug.Log(errMsg);
                CallBackToAndroid.RequestCallBack(false, communication.id, errMsg);
                return;
            }
 
            Debug.Log("SetMusicInfo -> " + dataJson);
            musicSoundController.UpdateMusicInfo(musicInfo);
            CallBackToAndroid.RequestCallBack(true, communication.id, "");
        }

序列化：

var info = new MusicInfo()
            {
                author = "",
                localCoverPath = "",
                name = "",
                netCoverPath = ""
            };
            var musicCommunication = new Communication()
            {
                id= 0,
                data = JsonUtility.ToJson(info)
            };
            JsonUtility.ToJson(musicCommunication);
